Is my video card upgradable?

IS there somewhere i can purchase a pretty good video card that supports VGA and multiple monitors that can be inserted into the express card slot or connected by USB or 4 pin firewire to be used in combination with the built in card in my laptop (Toshiba Satellite A215 S4747 if it matters) any other suggestions for giving my graphics a major boost would also appreciated|||Unfortunately not. This is one of the biggest pitfalls of a laptop, the lack of ability to upgrade them in almost any way without practically replacing it.
